Gentoo Linux Security Advisory

Title: dpkg: Arbitrary code execution (GLSA 201612-07)
Severity: normal
Exploitable: local, remote
Date: December 04, 2016
Bug(s): #567258
ID: 201612-07

Synopsis

A vulnerability was discovered in dpkg which could potentially lead
to arbitrary code execution.


Background

Debian package management system.

Affected Packages

Package: app-arch/dpkg
Vulnerable: < 1.17.26
Unaffected: >= 1.17.26
Architectures: All supported architectures


Description

Gentoo Linux developer, Hanno Böck, discovered an off-by-one error in
the dpkg-deb component of dpkg, the Debian package management system,
which triggers a stack-based buffer overflow.


Impact

An attacker could potentially execute arbitrary code if an user or an
automated system were tricked into processing a specially crafted Debian
binary package (.deb).


Workaround

There is no known workaround at this time.

Resolution

All dpkg users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=app-arch/dpkg-1.17.26"
